What will be the values of ans, x, and y after the following statements are executed?执行以下语句后，ans，x和y的值是什么？int ans = 35, x = 50, y =50;if ( x >;= y){ans = x + 10;x -=y;} else {ans = y + 10;y += x;}
A: ans = 60, x = 50, y =100
B: ans = 60, x =0, y =50
C: ans = 45, x = 50, y = 0
D: ans = 45, x = 50, y = 50
A: ans = 60, x = 50, y =100
B: ans = 60, x =0, y =50
C: ans = 45, x = 50, y = 0
D: ans = 45, x = 50, y = 50
举一反三
- What will be the values of ans, x, and y after the following statements are executed? int ans = 35, x = 50, y =50; if ( x >= y) { ans = x + 10; x -=y; } else { ans = y + 10; y += x; }
- What will be the value of ans after the following code has been executed? int x = 90, y = 55, ans = 10; if ( x == y); ans *= 2;
- What will be the value of ans after the following code has been executed?执行以下代码后，ans的值是什么？int x = 90,y = 55,ans = 10;if ( x == y);ans *= 2; A: 10 B: 145 C: 20 D: No value, there is a syntax error 无值，语法错误
- 求微分方程[img=101x35]17da5f15503f795.png[/img] 的通解,实验命令为(). A: dsolve(Dy+2*x*y=x*exp(-x^2))ans=C1*exp(-x^2) + (x^2*exp(-x^2))/2 B: dsolve('Dy+2*x*y=x*exp(-x^2)','x')ans=C1*exp(-x^2) + (x^2*exp(-x^2))/2 C: dsolve('Dy+2*x*y=x*exp(-x^2)')ans=C1*exp(-x^2) + (x^2*exp(-x^2))/2
- 已知ans='y'，则表达式ans=='y' or 'Y'的值为________________________。
